将两个小页面（一个带有列表列表，一个不带有列表列表）对齐到顶部？

Question

我已经知道两个带有 [t] 的小页面在顶线的基线对齐，而不是在各自的框/容器的顶部对齐；然而，这有些不同：当我使用一个带有一个字母的小型页面和一个带有 lstlisting 的小型页面，并尝试将它们对齐在顶部，如下面的 MWE 所示，我得到了这个（使用lua-visual-debug）：

我真的不明白——是什么把列表小页面向下推，换行符？那是从哪里来的？我怎样才能让这两个项目在顶部对齐（这样列表小页面就A保持在原处 - 列表+小页面垂直向上移动以匹配它）？

顺便说一句，请注意下面的 MWE - 第二个示例，其中有两个带有列表的小页面，可以毫无问题地运行：

\documentclass{article}

\usepackage{listings}

Answer 1

方法listings是使用aboveskip和，belowskip其初始设置为\medskipamount：

\begin{lstlisting}[aboveskip=-1.4\medskipamount]

代码：

\documentclass{article}

\tracingonline1
\tracingoutput1
\tracingparagraphs1
\usepackage{lua-visual-debug}
\usepackage{listings}
\usepackage{unravel}
\makeatletter
% \def\rst{\gdef\everypar={\setbox \z@ \lastbox }}
% \def\rst{\gdef\everypar##1{##1\unvbox}}
\def\rst{\leavevmode\unskip \lastbox\hfill} % \unvbox \z@ \lastbox \leavevmode \unhbox\z@
\makeatother

\begin{document}

Test sentence test sentence test sentence test sentence test sentence test sentence test sentence test sentence test sentence test sentence test sentence test ...

\hfill

\begin{minipage}[t]{\dimexpr\textwidth-2\parindent-2.2em}%
% }
%\vspace{-1.2\baselineskip}
\begin{lstlisting}[aboveskip=-1.4\medskipamount]

Answer 2

\vspace{-1.2\baselineskip}好吧，我找到了一个手动解决方法，即在第二次启动后立即使用{minipage}；然后输出如下：

... 我猜，这就是[t]+[t]所期望做的。

我使用该unravel包逐步遍历关键部分，并在 meld 中比较这些日志；问题似乎减少为\everypar两次运行的不同（参见下面的评论） - 所以我尝试了一些弹出的命令（\unvskip，\lastbox- 所有我不理解的命令并且找不到快速参考），但我无法控制它们 - 所以最后我只是在那里添加了一个 \vspace，它似乎起作用了（我之前也尝试过 \vspace，但是由于我把它放在其他地方所以它不起作用）。

无论如何，代码是：

\documentclass{article}

\tracingonline1
\tracingoutput1
\tracingparagraphs1
\usepackage{lua-visual-debug}
\usepackage{listings}
\usepackage{unravel}
\makeatletter
% \def\rst{\gdef\everypar={\setbox \z@ \lastbox }}
% \def\rst{\gdef\everypar##1{##1\unvbox}}
\def\rst{\leavevmode\unskip \lastbox\hfill} % \unvbox \z@ \lastbox \leavevmode \unhbox\z@
\makeatother
